Member shall not result in the dissolution of the Company or in the
cessation of the interest of the Member in the Company. The withdrawal or
resignation of the Member or the dissolution of the Member shall not, by
itself, constitute a dissolution of the Company.

                  (d) Upon the occurrence of any event that causes the last
remaining member of the Company to cease to be a member of the Company, to
the fullest extent permitted by law, the personal representative of such
member is hereby authorized to, and shall, within 90 days after the
occurrence of the event that terminated the continued membership of such
member in the Company, agree in writing (i) to continue the Company and
(ii) to the admission of the personal representative or its nominee or
designee, as the case may be, as a substitute member of the Company,
effective as of the occurrence of the event that terminated the continued
membership of the last remaining member of the Company in the Company.

                  (e) Notwithstanding any other provision of this
Certificate of Formation or of the Agreement, the bankruptcy of the Member
or any Special Member shall not cause the Member or Special Member,
respectively, to cease to be a member of the Company, and upon the
occurrence of such an event the business of the Company shall continue
without dissolution.

not, prior to the date which is one year and one day after the termination
of the Indenture and the payment in full of the Transition Bonds, any other
amounts owed under the Indenture, including, without limitation, any
amounts owed to third-party credit enhancers, and any amounts owed under
any swap or hedge agreement, acquiesce, petition or otherwise invoke or
cause the Issuer to invoke the process of any court or government authority
for the purpose of commencing or sustaining a case against the Issuer under
any federal or State bankruptcy, insolvency or similar law or appointing a
receiver, liquidator, assignee, trustee, custodian, sequestrator or other
similar official of the Issuer or any substantial part of its property, or
ordering the winding up or liquidation of the affairs of the Issuer,
provided, however, that nothing in this Section 8 shall constitute a waiver
of any right to indemnification, reimbursement or other payment from the
Company pursuant to the Agreement.

                  (b) To the fullest extent permitted by law, the Member
and each Manager and Special Member hereby covenants and agrees (or shall
be deemed to have hereby covenanted and agreed) that, until all of the
Bonds and all amounts owed under the Indenture have been paid in full, the
Member and such Manager will not consent to, or make application for, or
institute or maintain any action for, the dissolution of the Company under
Section 18-801 or 18-802 of the Act or otherwise.

                  (c) In the event that the Member, any Special Member or
any Manager takes action in violation of this Section 8, the Company shall
file an answer with the court or otherwise properly contest the taking of
such action and raise the defense that the Member, the Manager or the
Special Member, as the case may be, has agreed in writing not to take such
action and should be estopped and precluded therefrom and such other
defenses, if any, as its counsel advises that it may assert.

                  (d) The provisions of this Section 8 shall survive the
termination of the Agreement and the resignation, withdrawal or removal of
the Member or any Manager or the Special Member.

                  SECTION 9. Conflict. In the event of any conflict or
inconsistency between the provisions of this Certificate of Formation and
of the Agreement, the provisions of this Certificate of Formation shall
govern.
